NFSC 100 EXAM 3 WITH 100% DETAILED CORRECT ANSWERS 2025/2026
STUDY SET, Exams of Health sciences
atherosclerosis risk factors - ANSWERhigh LDL, low HDL, smoking, insulin
resistance, diabetes, obesity, unhealthy diet
definition/health risks of atherosclerosis - ANSWERcholesterol buildup in
arteries causing obstruction of blood flow; blood clot formation, plaque
ruptures, damaging arteries
scavenger receptors - ANSWERreceptors on macrophages and other cells that
bind to numerous ligands, such as bacterial cell-wall components, and
remove them from the blood
macrophage foam cells/atherosclerosis - ANSWERoxidized LDL accumulates in
macrophages, which are then known as foam cells; foam cells form the fatty
streaks of the plaques of atheroma in the arteries
response-to-injury hypothesis - ANSWERthe initial event in atherosclerosis is
injury to the endothelium, secondly, leucocytes, primarily monocytes,
migrate to the area of injury.
, in vitro models of atherosclerosis - ANSWER
which nutrients are more necessary during lactation? why are these needs
increased? - ANSWERcarbs, support growth and development of baby and
breastfeeding; folic acid, helps develop baby's brain and spinal cord; iodine,
encourages healthy thyroid; vitamin d, prevents rickets; iron, needs of fetus
are high; calcium, absorption doubles during pregnancy; vitamin b12, assists
folate in new cell formation, energy, protein, zinc
tips for women breastfeeding - ANSWERbegin within one hour of birth, talk
to a healthcare professional, no artificial nipples or pacifiers for infants, no
food or drink other than breast milk unless indicated
oxytocin and prolactin - ANSWERoxytocin is a peptide
hormone/neuropeptide that supports social bonding, sexual reproduction,
childbirth, and the period after childbirth; prolactin is the hormone that tells
the body to make breast milk when a person is pregnant or breast-feeding,
produced in pituitary gland
benefits of breastfeeding for baby/mother - ANSWERbaby: antibodies help
fight off viruses and bacteria, lowers risk of having asthma or allergies, babies
who are breastfed exclusively for the first 6 months, without any formula,
have fewer ear infections, respiratory illnesses, and bouts of diarrhea;
mother: burns extra calories, releases oxytocin, which helps uterus return to
its pre-pregnancy size and may reduce uterine bleeding after birth, lowers
risk of breast and ovarian cancer
when are solid foods introduced? why? - ANSWER4-6 months; ability to
swallow non-liquids develops, can sit with support at 6 mo., begins chewing
and grasping objects
